I bisected this one because I was curious how this could happen, and it
was broken quite explicitly by commit e818c01a:
commit e818c01ae6e7c54c7019baaf307be59d99ce80b9 (HEAD)
Author: Daniel P. Berrangé <[email protected]>

qapi: drop unused QCryptoBlockCreateOptionsLUKS.detached-header
The 'detached-header' field in QCryptoBlockCreateOptionsLUKS
was left over from earlier patch iterations.
Acked-by: Markus Armbruster <[email protected]>
Signed-off-by: Daniel P. Berrangé <[email protected]>
The test case demonstrates that it actually wasn't unused.
If we don't want to reintroduce the field in QAPI, we need to explicitly
delete it from the QemuOpts in block_crypto_co_create_opts_luks() before
block_crypto_create_opts_init() creates a QCryptoBlockCreateOptions from
the given options and fails now that this option doesn't exist any more.
